Not working after installing R2 release of the RelaSense SDK

[kosowski]

After updating the SDK to the R2 release (available at http://makebettercode.com/realsensesdk/en) the library is not working. The call to PXCSenseManager.CreateInstance() returns always null.

It was working great with the previous release. Any plans to upgrade? Thanks!

I am experiencing the same problem

[faluck]

does anyone still have the installer of the previous SDK?

[badlogic]

Sorry, folks, i'm currently extremely busy with work and won't have time to look into this for the next few weeks. If anyone wants to try and fix it i may be able to give some guidance. The build instructions are in the README.md.

i suppose the underlying problem kosowski and I are facing are somehow of similar nature

senseManager = PXCSenseManager.CreateInstance(); senseManager.EnableStream(StreamType.STREAM_TYPE_DEPTH); senseManager.EnableHand(); handModule = senseManager.QueryHand(); senseManager.Init();

        handData = handModule.CreateOutput(); // <- this returns null and crashes the program

running the camera without handData works fine though

[badlogic]

Could you consult the latest real sense SDK docs and see if the requirements regarding streams etc. changed? Also, is handModule null or is handData null? From your description it appears that hand module is actually null and the line you highlight crashes. On Apr 12, 2015 8:57 AM, "faluck" notifications@github.com wrote:

[faluck]

you're right, handModule is indeed null

System.out.println(senseManager.EnableHand());

gives me

PXC_STATUS_ITEM_UNAVAILABLE

[faluck]

oh and ill check the docs now

[badlogic]

In that case I'd check with the SDK 2 docs if anything changed regarding the initialization. Best case: there's a change log detailing the changes. Worst case: you have to check the new docs. On Apr 12, 2015 9:55 AM, "faluck" notifications@github.com wrote:

okay i found the doc (https://software.intel.com/sites/default/files/managed/af/a1/realsense-sdk-gold-release-notes.pdf)

under "Frameworks Support (C#, Unity, Web support, Java and Processing): Issue" it says:

Advanced streaming through the PXCMCaptureManager interface does not work as designed. The function LocateStreams may return failed on valid stream requests.

Avoid using the LocateStreams function. Use PXCMSenseManager for color/depth streaming.

and under "Hand Tracking and Gesture Recognition:" it says:

In a scenario when one application is setting the camera profile (resolution, FPS etc.) to an unsupported configuration by Hands, accuracy might be impacted Ensure camera profile is set to one of the supported Hands configurations

other than that i couldn't find anything relevant

[badlogic]

Can you try the samples that come with the SDK? Do those work? On Apr 12, 2015 10:26 AM, "faluck" notifications@github.com wrote:

that works, the light on the realsense camera briefly goes when i try to run the code but could there be some interference with my laptop camera?

[Morgam]

I have the same problem as kosowski, that is, PXCSenseManager.CreateInstance() returns always null. I also tried PXCSession.CreateInstance(), which returns null as well. I assume that this is different issue than faluck is experiencing as I can get senseManager instance in the first place (and the camera doesn’t seem to switch on). I did as told in https://github.com/libgdx/gdx-realsense in setting up the project. I first tried gdx-1.5.5. and subsequently versions 1.5.0 and 1.4.1, and had the same problem.

I have Intel RealSense SDK 4.0.0.52526 (I haven’t tried earlier versions). Camera and SDK examples (in C#, Java and C++) work, as well as SDK Capture Viewer.

In my view, there is something broken in libGDX RealSense SDK Integration, which I would very much get working. Thank you for starting this project!!

[Morgam]

Did anyone solve the issue kosowski and I are having?

I would really appreciate any help you could give...

[faluck]

any updates?

[badlogic]

I'm afraid not. As i said, you may try to build the bindings against SDK 2 following the instructions in the README of this repo. I'll likley not get to look into this in April, day job is keeping me busy. On Apr 22, 2015 10:18 AM, "faluck" notifications@github.com wrote:

I met same issue. Can not running by Eclipse.

[alexzhang7801]

Why not set session in the initial part of RS start?

[alexzhang7801]

class PXCSession This class defines a standard interface for maintaining the SDK context. This application can query and create instances of I/O and algorithm module implementations.

What's the last SDK that works with lib-gdx? Thanks

[alexzhang7801]

Hi Man, current lib-gdx version 1.0.0. Thanks.

Sorry, misunderstood me. Which RealSense SDK is reported as working with lib-gdx v1.0? Since the last one doesn't work. thanks

For everybody who wants an RSSDK which works with the current lig-gdx here's the link: https://mega.co.nz/#!gAABGbpA!hBDf6aJFCvPy2svQWPJZ9EVdHPMNFYbuizBITbER63o

Thanks to @alexzhang7801 for the help.

I can't preform a landmark query points, an exception is thrown. "a heap has been corrupted" and it references this: ntdll.dll

Any guess? Can you help @badlogic ?

thanks

Hi Rafael, Could you support capture image form eclipse IDE? thanks

Yes I can see the depth and color image, preform face tracking and pose estimation. But I can't find the landmark points the exception is thrown.

[ramyalsharif]

anything new on this?

PXCSenseManager.CreateInstance()

returns null

[QuocZung]

I'm having the same problem: PXCSenseManager.CreateInstance() returns always null. I'm a student and pretty new to this so pls patient with me. I installed RealSense SDK 2.0 and its working fine with Viewer, C++ examples but not with C#. Any solutions pls?
